Android Marshmallow: Test permissions with Espresso?

With the new release of the Android Testing Support Library 1.0, there's a GrantPermissionRule that you can use in your tests to grant a permission before starting any tests.

@Rule public GrantPermissionRule permissionRule = GrantPermissionRule.grant(android.Manifest.permission.ACCESS_FINE_LOCATION);

Kotlin solution

@get:Rule var permissionRule = GrantPermissionRule.grant(android.Manifest.permission.ACCESS_FINE_LOCATION)

@get:Rule must be used in order to avoid java.lang.Exception: The @Rule 'permissionRule' must be public. More info here.

The accepted answer doesn't actually test the permissions dialog; it just bypasses it. So, if the permissions dialog fails for some reason, your test will give a false green. I encourage actually clicking the "give permissions" button to test the whole app behaviour.

Have a look at this solution:

public static void allowPermissionsIfNeeded(String permissionNeeded) {    try {       if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M && !hasNeededPermission(permissionNeeded)) {        sleep(PERMISSIONS_DIALOG_DELAY);        UiDevice device = UiDevice.getInstance(getInstrumentation());        UiObject allowPermissions = device.findObject(new UiSelector()          .clickable(true)           .checkable(false)           .index(GRANT_BUTTON_INDEX));        if (allowPermissions.exists()) {          allowPermissions.click();        }       }     } catch (UiObjectNotFoundException e) {      System.out.println("There is no permissions dialog to interact with");    }   }

By the way, as this answer has been a popular one, we added PermissionGranter to Barista, our tool above Espresso and UiAutomator to make instrumental tests green: https://github.com/SchibstedSpain/Barista check it out, because we will maintain it release by release.

Give a try with such static method when your phone is on English locale:

private static void allowPermissionsIfNeeded() {    if (Build.VERSION.SDK_INT >= 23) {        UiDevice device = UiDevice.getInstance(getInstrumentation());        UiObject allowPermissions = device.findObject(new UiSelector().text("Allow"));        if (allowPermissions.exists()) {            try {                allowPermissions.click();            } catch (UiObjectNotFoundException e) {                Timber.e(e, "There is no permissions dialog to interact with ");            }        }    }}
